What is the primary purpose of the plugin-anatomy skill?

It provides a standardized knowledge base for creating, inspecting, and validating the structure of Claude Code plugins, including commands, agents, and hooks.

What are the required fields for a Claude Code plugin manifest?

Every plugin requires a plugin.json file within the .claude-plugin directory containing the name, version, description, and author fields.

Does this skill help with MCP integration?

Yes, it includes documentation and templates for connecting external MCP (Model Context Protocol) servers to your Claude Code plugin environment.

How does it distinguish between Commands and Skills?

Commands are active slash commands invoked manually by users, while Skills are passive knowledge bases that Claude automatically triggers based on context and keywords.

Can I use this to automate tasks in Claude Code?

Absolutely; it details how to implement event-driven hooks like SessionStart, PreToolUse, and PostToolUse to trigger bash scripts or LLM-driven prompts.
